This research project, carried out by Professor Phillipe Guyot-Sionnest and his research group at the University of Chicago, addresses questions of vibrational energy flow between adsorbed molecules and metal surfaces. Supported by the Analytical and Surface Chemistry Program, this project examines the transfer of vibrational energy between adsorbed diatomic molecules and the metal surface, as well as the effect of vibrational excitation on the dynamics of small molecule reactions at these surfaces. The development of fast infrared laser sources needed for these studies forms another focus of this research effort. The basic information obtained from these studies is useful for our developing understanding of important heterogeneous processes such as catalysis and semiconductor device processing. The detailed understanding of the dynamics of energy exchange and reaction at solid surfaces is the goal of this research project. Fast infrared laser probing of these processes is used to obtain a detailed picture of energy transfer and reaction at metal surfaces. This basic information impacts technologically important areas such as heterogeneous catalysis and electronic materials processing.

该研究项目由芝加哥大学的Phillipe Guyot-Sionnest教授和他的研究小组进行，解决了吸附分子和金属表面之间的振动能流问题。 在分析和表面化学计划的支持下，该项目研究了吸附的双原子分子和金属表面之间的振动能量转移，以及振动激发对这些表面小分子反应动力学的影响。 这些研究所需的快速红外激光源的发展形成了这项研究工作的另一个重点。 从这些研究中获得的基本信息是有用的，为我们发展的重要多相过程，如催化和半导体器件加工的理解。 详细了解固体表面的能量交换和反应动力学是本研究项目的目标。 这些过程的快速红外激光探测用于获得金属表面能量传递和反应的详细图像。 这些基本信息影响了重要的技术领域，如多相催化和电子材料加工。
